DIY - guibo joint / flex disc / universal joint replacement procedure thread

Feeling some drivetrain/shifting slack - and my car being at 138K miles and 8-ish years old - I figured I'd go ahead and replace my guibo joint / flex disc / universal joint. I haven't yet seen any pictures on doing this yet, so I figured I'd go ahead and do it / post pictures.

The basic procedure is:

1. Drop exhaust system
2. Drop heat shields
3. Drop transmission mount
4. Drop driveshaft (CV joint at rear, center mount, then guibo joint)

So far I have the exhaust system down and the heat shields off. Had to take the car down to shut the garage door, but will hopefully have it in the air again and finish in the next few days.

Because the space in which I chose to do this is limited, I'm going to make an attempt to skip #3 and replace the guibo joint without dropping the transmission mount. Stay tuned for updates.

See pictures / procedure --> here.
 

Let us know if you feel a difference... Great thread BTW, I'm not a DIYer but I'm sure this will be useful to many members.

I really really really appreciate this Keif!

Keif coming through in the clutch again

thanks keef .....looking for you final result

amazing DIY...props man.

i just had mine done at the dealer

they charged the warranty company about $1000

i had rough shifts, i wonder if that would fix the problem

definitely will make it better...i had the same problem. jesus...$1000 for the guibo???

wow what a rip

+1. If I had a lift, this would almost be a trivial task.

it's really like $150 for the guibo. How can they justify $850 in labor? that's like 10 hours worth of labor at most shops

Still all kinds of jealous of your pit!

Could you please list all the parts needed to do this job? I am going to get all the parts together and have my mechanic do it.

Thanks!

The guibo joint / flex disc / universal joint, part #2 here was the only part I bought.

Tonight I took the driveshaft down, put the new guibo joint on, and bolted the driveshaft back up. Tomorrow I should be hanging the exhaust and bolting everything back up. Also, you do NOT have to drop the transmission mount -- there is a gap where you can hold the necessary bolts at the guibo joint with a 16mm crescent wrench with the transmission mount in place.

yea but its the warranties job to complain about getting ripped off

when i know i am being ripped off, i raise hell

How about a video of how it sounds without the exhaust?

I just got mine replaced yesterday under the SIB that covers the E65, otherwise it would have been about $800!

Looking for a fire extinguisher, then I plan on it. =]

Very cool. Been thinking of tackling this one myself - you beat me to it!

No go on the video without exhaust -- I couldn't find a fire extinguisher that wasn't behind glass. =( Next time I'll come prepared.

Finished everything up last night. It helps to have a second person when hanging the exhaust, so my dad came over to help. After hanging the exhaust in its rubber mounts, bolting everything back up was very easy. The exhaust system is sealing well and I have no parts left over.

While the old guibo joint didn't appear to have anything but hairline surface cracks in small places, replacing it definitely tightened up the little bit of slack in the drivetrain I felt when shifting and stopping/starting. Very happy with the results.

I will post up a few more pictures later today or this evening in case anyone is interested (mainly of the driveshaft and its various joints).

Final pictures posted. Will label and add descriptions and stuff later tonight.

I saw u did a great with univeirsal joint. What the difference? I want change mine I have some metal soung coming when i shift from R to D. What you think?

There was a little slop in the shifting, mainly while moving, but none now. Is the sound coming from the transmission itself, or somewhere along the driveshaft?

Some time i feel like it comes from transmition,but some time i hear it coming from the back , but some time it dose not happen it all 10% of the time. I show one mech he said transmtion another UJ

Try having someone else shift while you listen under the car to see how far back the noise is coming from. There is a crossmember underneath that you can use as a point of reference. As you can see here and below, the crossmember is roughly where the middle universal joint is (the bolts coming down from the body on the left and right are where the crossmember bolts on). There is also a similar joint at the very rear of the driveshaft.

I can be all 3 parts central mount UJ and rear joint ? how much time did take for you to do all work?
